If you actually want an adventure/strategy game with a good storyline, I'd highly suggest the Myst series (though there's not much story in the first one, it really picks up in Riven and Revelations).
And about
www.mmorpg.com, yeah it's been around forever. I have no idea why Guild Wars is up there, but I understand Everquest II. Everquest II has really picked itself up in the last couple expansions, as has FFXI. Though World of Warcraft still has the highest player base, I think, of roughly 8M or so, which is absolutely huge.
